Title: Ink jet recorder
Inventor: MAKINO MASAYUKI
IPC: B41J2/12
Filed: 1981-08-04
Abstract: PURPOSE:To raise the accuracy of printing by a method in which the magnitude of the deflected amount of ink is detected by the output pulse of an image sensor and the deflected amount is kept at a predetermined value by varying the flow rate of ink and charging voltage. CONSTITUTION:Since ink supplied from an ink pump 19 and jetted through a nozzle 20 is divided into regular ink droplets rows 24 by the vibration of a piezo-electric vibrator 21, a charge electrode 26 is placed the place where ink is divided and a certain voltage of pulse is given by a charge circuit 25, whereupon ink droplets are electrically charged, deflected between deflecting electrodes 28a and 28b, and pass by the front side of the image sensor 22. At this time, the deflected condition of ink droplets is reflected on the image sensor 22 by light emitted from a luminous element on the opposite side. Then, a counter 16 is cleared by sample pulse (b) from a printing control circuit 15, a count value at a standard deflection value is set in the register 17, the counter 16 is worked until output (c) from the image sensor 2 appears, and then the values of the counter 16 and the register 17 are compared in a count value comparator circuit 18.

Abstract: PURPOSE:To prevent a printing head, a paper and a ribbon from being staggered or rubbed and print clearly, by a construction wherein a platen holder is pivotally supported on a frame through an aligning mechanism, and both end support parts of the holder are elastically supported through an elastic body. CONSTITUTION:The platen holder 3 is supported by engaging the aligning mechanism 9 which consists of a V-groove 10 and a projection 11, and simultaneously inserting both end supporting arm parts 12 into inserting holes 14. An elastic body 13, particularly, a front affixed part 13A thereof is provided with such a thickness that it is compressed by a predetermined amount in the supported condition and a reactional force thereof creates an appropriate pressure at the press engaging part (the groove 10 and the projection 11) of the aligning mechanism.

Title: Microscope for receiving optical signal
Inventor: NAGIRA YASUHISA
IPC: H04B10/112
Filed: 1982-07-15
Abstract: PURPOSE:To receive signals through both visual observation and acoustic sense by making light flux from an objective lens system incident to a photodetector, taking out the change of strength of an originating light source as an electric signal and then converting the electric signal into a voice signal. CONSTITUTION:A part of light flux from the objective lens system 1 is observed by an eyepiece system 5 and a part of the light flux is made incident to a photodetector 7. When a light passing area of a diaphragm 6 is displayed on a reticle 4 to observe the area by the naked eye, the light flux can be precisely catched by the photodetector 7. The incident light to the element 7 is converted into an electric signal by a photometric circuit 81. When the electric signal is shaped by a waveform shaping circuit 82, an ON-OFF signal only due to a signal waveform is obtained from a peak value following circuit 85 and a level controlling circuit 86 while considering a non-signal output due to the strength change of background light. The ON-OFF signal from the circuit 82 controls ON and OFF of a gate circuit 83 and controls the connection and disconnection of the audible frequency of an oscillator 87 to obtain an audible signal.

Title: Photo-setting composition for antimicrobial film
Inventor: KATO HIROSHI
IPC: C09D4/02
Filed: 1995-05-22
Abstract: PURPOSE: To obtain a composition capable of simply forming an antimicrobial film by applying the composition onto a substrate and then irradiating the coated substrate with light, especially ultraviolet rays. CONSTITUTION: This photo-setting composition for an antimicrobial film comprises (A) 100 pts.wt. acrylate-based polymerizable monomer containing >=10wt.% polyfunctional acrylate-based polymerizable monomer such as tetraethylene glycol diacrylate, (B) 0.001-0.5 pt.wt. (expressed in terms of the amount of silver) silver salt such as silver nitrate and (C) 0.1-5 pts.wt. photoinitiator. The resultant film is not only capable of manifesting high antimicrobial activities but also excellent in properties such as film strength, adhesion, transparency and lubricity. Since the silver ions are usually unstable to light, water, acids, alkalies, etc., there are problems in preservation stability of the photo-setting composition for the antimicrobial film. The problems in the preservation stability, however, can be reduced by regulating the moisture content in the composition to <=1000ppm.
